Fun Fact

Eels have “pharyngeal jaws” – a second set of jaws hidden in their throat that they use to help swallow their prey. Usually they bite with their oral jaws to capture, then their pharyngeal jaws come forward to grip and retract. 

 

Habitat: Found throughout the Indo-Pacific region, in the tropical waters of Australia. Often found in areas with seagrass as well as rocky reefs, and also possible to spot in tidal pools (look for them at Julian Rocks or Flatrock) 

 

Threats: This is one of the most widely spread and populous moray eel species but like many ocean creatures their habitats and prey species are potentially at risk from human behaviours. Issues such as climate change, pollution, bycatch, overfishing, habitat degradation are threats to these fish and the prey they depend on.
